LAMP.

SPECIFICATIN formingpart of Letters Patent No. 236,108, dated December28, 1880. Application filed September 3, 1880. (No model.)

To all whom it may concern:

Be it known that I, FREEMAN A. TABER, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Lamps; and I dohereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the artto whichit appertains to make and use the same, reference beinghad totheaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention, in the main, is based upon a class of fountain oil-lampsshown and described in Letters Patent ofthe United States issued tomyself on the 15th day of April, 1879, in

which the oil-fount, or the same and its inclosing-case, is combinedwith the hanger which suspends the lamp from the ceiling in such mannerthat the fount and case are susceptible of vertical sliding movements toand fro of the hanger and with respect to the shades or globes of thelamp, which are stationary with the hanger, by which means the fount andburner may be lowered and separated from the globes and ready access hadto the burners and the filling-orifice of the fount when trimming,lighting, or iilling of the lamp is necessary.

In my present lamp I employ an oil-fount extending bodily to andconnecting directly with the Wick-reservoirs, in lieu of a commoncentral fount supplying by means of branch pipes the various burners, asin my patent above named, and I employ in place of said fount a shellwhich is a counterfeit of it, and serves to conceal the spring-boltswhich secure the movable portions of the lamp, the oil-fount passingthrough such shell, and with the burners,y

which are attached to it, being removable from the case which containsit, and the whole being substantially as hereinafter described. I alsoemploy as a novel feature in my present improvements a tube disposedwithin the wickreservoir, which supports the burner and contains thewick,such tube extending nearly from top to bottom of the saidreservoir, and serving to protect the oil therein from the disturbanceand. agitation due to the swinging of the lamp when applied torailway-cars or steamwick-reservoir.

The drawings accompanying this speciiication represent, in Figure 1, alongitudinal vertical section of a portion of a hanging lamp madeinaccordance with my invention; in Fig. 2, a vertical cross-sectionthrough the oil-reservoir, and Fig. 3 a vertical section through thehanger.

In said drawings, A represents the suspensory or hanger by which thelampis suspended from the ceiling of a railway-car or other apartment,or saloon of a Steamship, this hanger being of yoke form, and the lowerextremities of its arms terminating in horizontal ringsleeves B B, whichserve to uphold the globes or shades O O which surmount the burners.

Centrally of the lower part of the hanger I add a horizontal circularcap or disk,l), which serves not only as a cover to the counterfeitoil-fount, but as a guide to vertical rods a a, erected upon the shellor case E containing the oil-fonnt proper, E', which rods slide inpassages b b in said disk D, and by means of which the oil-fount andburners may be lowered and separated from the shades or globes, therebyenabling ready access to be had to such fount and burners when trimming,cleaning, or lighting the wicks is necessary or the fount needsreplenishing with oil. Should it be desirable to remove theoil-reservoir altogether, it may be lifted out of its inclosing-casewhen the latter is lowered.

To uphold the oil-fonnt and burner and the case which contains them whenin their highest position, I add to the opposite sides of the interiorofthe cylindrical central portion, F, ofthe case E, which contains theoil-fount E', springlatches G G, the lower ends of which are secured tothe lower part of the case, while their upper ends are formed withcatches or hooks b b to engage the upper part of the disk D, orices c cbeing formed in such disk to permit of passage of the ends of thelatches.

The cen tralcylindrical portion, F, ofthe case E resembles an oil-fount,but is in reality merely a hollow cylinder, while the ends of the caseextend laterally from it, and terminate each in a vertical tubular case,H, which con- IOO stitutcs a receiver for the wick-reservoir I, in whicheach end of the oil-fount E terminates.

The oil-fount E is a continuous vessel from end to end, and carries ateach extremity a burner, J, such burner being secured to the top of avertical tubular wick-reservoir, K, in which each end ot' the fountterminates, and which communicates directly with the interior of thefomit.

L in the drawings represen ts a vertical tube disposed within eachwick-reservoir l, this tube being of slightly less diameter than theinterior ot' the reservoir to provide a shallow annular chamber, d,between the two, and being erected upon and secured to the bottom of thesaid reservoir, the height of this tube or shield L being such as toextend above the openings leading from the oil-fount to the reservoir,as shown in Fig. l of the drawings. The tube or shield L serves to breakthct'orce of the swaying body of oil in the fomit, thereby preventingthe iiuctuation ot' the light, which now frequently occurs from theagitation of the body of oil contained in the main fomit acting uponthat contained in the wick-reservoir. To prevent to a certain extentswaying of the body ot' oil in the fount itself, I add to the interiorcentral portion of the latter a pendent tube, N, which is secured at itsupper end to the mouth of the filling-orifice O of the fount, a shallowspace, c, intervening between the lower end otl this tube and the bottomof the fonnt to permit of tilling ofthe latter.

Rings or handlcsff, placed equidistant from the center of the t'ount,may be added to the top of the latter to enable it to be readily liftedfrom its case should occasion require.

I claim- 1. The combination, substantially as hereinbefore set forth, ofthe stationary hanger and its cap, the oil-fount shell or receiverprovided with a cylindrical portion and movable up and down in thehanger, so that said cylindrical portion may be covered by said cap oruncovered, according to the direction ot' movement, and the oil-forintremovable from said shell or receiver.

2. The combination ot' the hanger carrying the shades or globes, theshell or case E, carried by and movable up and down in said hanger,locking devices for securing the shell in its raised position, and theoil-fount E', removable from shell E and provided at opposite ends withwick-reservoirs, substantially as hereinbet'ore shown and set forth.

3. The combination, with shell E and removable fount E', ot' thewick-reservoir K and the tubular shield L therein, extending up to orabove the point in the side ot' the reservoir at which the lattercommunicates with the i'ount, substantially as herein shown and setforth.

4. The removable oil-fount having a tubular central tube, and carryingreservoirs at its ends provided with internal tubular shields whichextend up from the bottom ofthe wickreservoirs to or above the height ofthe lateral communicating openings between the fount and thewick-reservoirs.

In testimony whereof I affix my signature in presence ot' two witnesses.
